WHEAT SCALPING AND CONDITIONING MACHINE.

Application filed May 10, 1916.

To all whom it may concern:

Be it known that I, JOSEPH H. HEISHMAN, a citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in lVhcat Scalping and Conditioning Machines, of which the following is a specification.

My invention relates to improved mechanism for treating wheat particularly, preliminary to grinding the same; the purpose being to provide for continuously and effectively scalping or removing the bran, for eliminating the undesirable berries and extraneous matter such as garlic and smut, and for properly conditioning the material.

- The invention is fully described in connection with the accompanying drawings illustrating the same in preferred form, and the novel features are clearly defined in the sub joined claims.

Figure l is a longitudinal elevation, showing the upper half of the casing raised and a portion of the lower casing broken away.

Fig. 2 is an end view showing the casing closed.

Fig. 3 is a cross-section on the line 38 of Fig. 1.

The horizontally arranged cylindrical casing 10, has its upper half hingedly connected, and is provided at one end with an inlet opening 11 for feeding in the stock, and at the other with a gate-controlled outlet 12 for the treated material, as hereinafter more fully described. At each end is also provided a suitable bearing 13, 13, for a centrally mounted horizontal shaft 14, to which rotary movement is imparted through a belt wheel 15, as indicated; and the inner walls of the cylinder, including its hinged cover portion, are provided with spirally arranged ribs 16, preferably formed as a se'parably secured wall lining so as to permit renewal when worn and modification of form if desired.

The rotary shaft 14 is specially constructed to Serve as an agitator device adapted to effectively remove the bran and all extraneous matter from wheat berries, and to break up the softer berries which are unsuited for grinding with the harder ones under treatment; while at the same time serving in connection with the spirally ribbed inner wall of the casing and the automatically regulated outlet 12, to regulatedly discharge the treated mater al from the cas- Speoification of Letters Patent.

ing. This improved construction comprises, as shown, a split Collar 2021 partably secured to the shaft 11 adjacent each end of the casing; longitudinal bars 22, 22, 22, 22, rigidly extending between said collars parallel with the shaft but spaced away from the latter and from each other so as to provide intervening spaces 25 and respectively; and a series of radially arranged paddle-blades 27 spacedly mounted upon each of said bars by means of pivotally engaged shank portions 28 thereof, so as to permit of their being independently ad justed to different angles with respect to the axis of the shaft and rigidly secured in such Each of these paddleblades is provided, as shown, with one or more openings or apertures 30 and edgewise recesses 31, forming restricted passageways for the Wheat berries. All the berry-contacting surfaces of each paddle are ribbed as indicated so as to effect a rubbing and crushing action upon the passing berries; and the berry-contacting surfaces of the bars 22 and collars 2021 are similarly ribbed for the same purpose. Certain of the bars 22 are fixed to corresponding parts of the split shaft collars 20, 20-, while the others are fixed to the other collar parts 21, 21 thus permitting of conveniently detaching the bars in pairs or groups to facilitate proper adjustment of the paddle blades.

The length of time during which the material fed into the casing at one end is subjected to the action of the rotary agitator mechanism described, before it is discharged from the casing at the other end, as well as the intensity of such action, may be readily varied as desired even with a fixed speed of rotation. The spirally ribbed inner walls of the casing are adapted to feed the centrifugally flung material toward the exit end of the casing, and this feeding-onward action may be varied by the relative setting of the angularly adjusted paddle blades, so as to produce a pressing action upon the movable gate 35 which controls the outlet opening 12 of the casing. The rapidity of discharge however is independently regulated, and automatically controlled as determined, by providing a variably adjusted resistance to such feed pressure upon the gate. This is accomplished as shown by employing a weight-beam 4L0, pivoted at a fixed point 11 and having its short arm 42 connected by a link 43 to the gate; so that any required resistance to the opening movement of the gate maybe secured and malntalned by corresponding ad ustment or variation of the weight upon thebeam. An adjustable.

spring 45 secured to the weight-beam 40 as shown, serves to counterbalance said arm 1f deslred.

The operation of my improved machine is simple, and has already been made clear in connection with the foregoing description. The stock operated upon is subjected to constant and very effective treatment'by the rubbing and pressing action incident to its circular movement between the ribbed sur faces and restricted passage ways of the rotary agitator device,- which action is con- 'iinued at all stages of its gradual longitu- Copies of this patent may be obtained for within the casing so as to impede the free movement of thegrains \Vhat I claim is: V
